Substitute Part Grouping Explanation

Substitute parts are selected strictly based on parametric equivalence. The defining parameters for equivalence in the Diodes, Rectifiers category for the BAT54BR are: diode configuration (2 Pair Series Connection), Schottky technology, maximum reverse DC voltage (30 V), average rectified current per diode (200 mA), maximum forward voltage at rated current (1 V @ 100 mA), reverse recovery time (5 ns), reverse leakage current (2 µA @ 25 V), junction operating temperature range (-65°C ~ 125°C), surface mount type, and package (SOT-363 / 6-TSSOP, SC-88). Compliance with ROHS3 and REACH is also a requirement. Only models matching every listed parameter are considered for substitution.
